Successfully fired up a Porsche 996 GT3 on our 997.1 (Now 996/997.1) Package. Specifically, a 4.2L 996 GT3. Also, make sure your fuses are good. :)
In addition, we are working on making the integration work a bit more seamlessly to hide things that are not applicable for a given model or type. It will also allow you to choose individual subsystems to turn off, for use in a mostly-not-stock race setup.
